Client of mine using your Feedback Designer wants the "Please enter a correct value for" error messages in red and bigger... I could swear they were in red before. I was guessing I just had to change the class ".iwebserror"..but when I looked it is "red" alreadt... for some reason my errors are showing the grey.

Here is a link to the Google Chrome developer tool view where you can see the SPAN for what I would think the error message container is (font color=red), ends and goes back to a NORMAL container.

I tested with the current release 70.07.04 and reproduced the error you mentioned.
I guess you have to wait on the official release of FeedbackDesigner 70.07.07 (62.06.06)
When you install this version you will see that not only the errors are within the div.iswebserror, the inline styling is also removed in favour of external module-css (CFD.512.css)
Hope that helps
